“Meanwhile, no significant difference was found in the flexural moduli of the KRRRK, KRKRK, KKRKK and KKKKK composites……However, the KHRHK composites exhibited the largest flexural modulus of 9.1 GPa with an increase of 96% due to better interfacial properties. ”
This sentence does not still give any motivation of the claimed negligible difference. The elastic modulus of KHRHK is 9.1 GPa, that of KKKKK is about 6.5 MPa. In my opinion this is a relevant difference, having in mind the standard deviation detailed in Figure 7b. Similar observation is for the flexural strength in Figure 7a.

是我没解释清为什么KKKKK复合材料弯曲模量低吗？

“In my opinion this is a relevant difference, having in mind the standard deviation detailed in Figure 7b. Similar observation is for the flexural strength in Figure 7a.”这个是什么意思？relevant difference 是什么？我应该从哪方面着手解释呢？
